Rule 14
Avoiding Contact
Rule 14 - AVOIDING CONTACT
A boat shall avoid contact with another boat if reasonably possible.
However, a right-of-way boat or one entitled to room or mark-room
(a) need not act to avoid contact until it is clear that the other boat is not keeping clear or giving room or mark-room, and
(b) shall be exonerated if she breaks this rule and the contact does not cause damage or injury.
Relevant Definitions
Keep Clear
A boat keeps clear of a right-of-way boat
(a) if the right-of-way boat can sail her course with no need to take avoiding action and,
(b) when the boats are overlapped, if the right-of-way boat can also change course in both directions without immediately making contact.
Clear Astern and Clear Ahead; Overlap
One boat is clear astern of another when her hull and equipment in normal position are behind a line abeam from the aftermost point of the other boat’s hull and equipment in normal position. The other boat is clear ahead. They overlap when neither is clear astern.
However, they also overlap when a boat between them overlaps both.
These terms always apply to boats on the same tack.
They apply to boats on opposite tacks only when rule 18 applies between them or when both boats are sailing more than ninety degrees from the true wind.
Room
The space a boat needs in the existing conditions, including space to comply with her obligations under the rules of Part 2 and rule 31, while maneuvering promptly in a seamanlike way.
Mark
An object the sailing instructions require a boat to leave on a specified side, and a race committee vessel surrounded by navigable water from which the starting or finishing line extends. An anchor line or an object attached accidentally to a mark is not part of it.
Mark-Room
Room for a boat to leave a mark on the required side.
Also,
(a) room to sail to the mark when her proper course is to sail close to it, and
(b) room to round the mark as necessary to sail the course.
However, mark-room for a boat does not include room to tack unless she is overlapped inside and to windward of the boat required to give mark-room and she would be fetching the mark after her tack.
